IMPROVEMENT IN 'QUILL-BOBBINS FOR'SPlNNlNG-lVlACHINES.

Specification forming part of Letters Patent No. 139,652 dated June 10,1873; application filed May 16, 1873. I

To all whom it may concern:

Be it known that I, DAVID BAss, Jr., of Woonsocket, of the county ofProvidence and State of Rhode Island, have invented a new and usefulImprovement in Quill-Bobbins for Spinning-Frames; and do hereby declarethe same to be fully describedin the following specification andrepresented in the accompanying drawings, of which- Figure 1 is anelevation or outer-side view, and Fig. 2 a longitudinal section, of abobbin constructed in accordance with my invention.

Quill-bobbins, as ordinarily made, consist of a thin tube of wood,sometimes hushed at either or each end, though as often without anybushing. Such bobbins while in use, in consequence of the ends of thewood being uncovered, soon become indented, battered, nicked, or splitat one or both ends.

Furthermore, with the common quill-bobbins whose bushings or upper endsare of wood easily indented, the bore of the' end or bushing is liableto be injured, grooved, creased, or split by the end of the spindleduring the process of applying the bobbin to the spindle, in which casethe bobbin is liable to become eccentric to the spindle, or work looseupon it, to the detriment of the spinning. These injuries not onlyafiect the proper operation of the bobbin, but soon render it unfit foruse.

It is very important to have a bobbin as light, or of as little weight,and as durable, as possible. I have discovered a mode of constructing aquill-bobbin by which I am not only able to employ a very lightmaterial, such as poplar wood, for its body, and to have such'body verythin, but to completely protect the ends of the body and head or headsof the bobbin from becoming split or nicked when l the bobbin is thrownupon the floor or upon either or each end of, or combine with, the

bobbin-body A, made tubular, or with a bore extending through from oneto the other end of it, a cap or crown, Bfwhich I usually make of horn,rawhide, or'some other like material sufficiently hard to withstand theblows to which it is liable while in use. This cap or crown unites thequalities of a bushing to receive the spindle and support the bobbinthereon with those of a cap to extend over and cover the end of thebobbin, so as to pro tect it from being split or injured. To this endthe crown is formed in transverse section in the manner represented inFig. 2, viz., with a head, h, and neck b,its bore a being trumpetshapedor otherwise, as shown. The neck b is cylindrical, and extends into thebody the requisite distance until the end of the body abuts closelyagainst the shoulder c of the head, and is covered thereby, the surfacesin contact being glued or cemented together.

I do not confine my invention to horn or rawhide forthe crown of the endof the body or quill of the bobbin, although such material answers thepurpose, but I intend to use any other substance having the requiredqualities.

I am aware that it is not new to protect the head of a double-headed orthimble bobbin by a layer of rawhide or horn fixed upon the outersurface of such head; I therefore make no claim thereto.

I claim as a new or improved manufacture- A quill-bobbin provided withathin tubular body, and at either or each end thereof with a protectioncrown-bushing, of horn or other proper hard material, so applied to thebody as to extend intoit and project over and upon and cover the endthereof, all substantially as described and represented. r
